Squished

On my morning walk, on a country road,
I saw a bird, a mouse, a toad
All flattened out, completely squished -
Not quite the ending they'd have wished.

Though traffic's light, these heedless three
Ignored precautions, unlike we,
Who'd look both ways before we'd cross;
Not doing so assured their loss.

The mouse, who runs and toad, who jumps,
Predictably would take such lumps
But I can't comprehend just why 
The bird did not take wing and fly.

I'm sure their brethren might await
A similar unlucky fate,
For crossing roads has such appeal
It warrants squishing 'neath a wheel.
